Video clip of the high-frequency clock during the speed of sound demonstration measurement

As this short clip plays, you'll hear the wood blocks clap together as the clock disc appears under the illumination of red and blue flashes.  This is repeated once. Replay the clip by clicking on the play button or the move window. (If the movie doesn't appear, click here to download the movie in Video for Windows or QuickTime format:  VFW | QT.)
